HC-12 Wireless Serial Port Communication Module 433MHZ HC12 SI4463
HC-12 wireless serial port communication module is a new-generation multichannel embedded wireless data transmission module.
HC-12 wireless serial port communication module is a new-generation multichannel embedded wireless data transmission module. Its wireless working frequency band is 433.4-473.0MHz, multiple channels can be set, with the stepping of 400 KHz, and there are totally 100 channels.
HC-12 Bluetooth module has a microcontroller which actually doesn’t have to be programmed by the user. For configuring the HC12 Wireless Module we simply use AT commands, which can be sent from an Arduino, a PC, or any other microcontroller using the serial port. For entering the AT command mode we just have to set the “Set” pin of the module to a low logic level.
The maximum transmitting power of module is 100mW (20dBm), the receiving sensitivity is -117dBm at baud rate of 5,000bps in the air, and the communication distance is 1,000m in open space.
With the HC-12 Bluetooth transceiver module you can send data between two devices at a great distance.
The module is equipped with an SI4463 Transceiver IC in combination with a STM8 microcontroller.
Communication via an Arduino is very easy via UART (RX and TX) signals.
it is very convenient for customers to go into application system. There is a PCB antenna pedestal ANT1 on the module, and user can use external antenna of 433M frequency band through coaxial cable; there is also an antenna solder eye ANT2 in the module, and it is convenient for user to weld spring antenna.
User could select one of these antennas according to use requirements. There is MCU inside the module, and user don’t need to program the module separately, and all transparent transmission mode is only responsible for receiving and sending serial port data, so it is convenient to use.
